Popular Messaging App Hacked, Is Working On a Fix, Yo

The student emailed TechCrunch detailing what he alleges are the results of the hack: “We can get any Yo user’s phone number (I actually texted the founder, and he called me back.) We can spoof Yos from any users, and we can spam any user with as many Yos as we want. We could also send any Yo user a push notification with any text we want (though we decided not to do that.)”

Yo founder Or Arbel confirmed to TechCrunch the app was “having security issues,” and that “some of the stuff has been fixed and some we are still working on. We are taking this very seriously.” He also said a specialist security team was involved to deal with the security problems.

We are working on the securities issues that came to our attention. We want you to know we take this very seriously.
